Cardiovascular Function in Hypothermic Anesthetized Man
Although hypothermia is being used as an adjunct to general anesthesia, its cardiovascular effects in man are not fully known. In this report the authors present the hemodynamic changes observed in patients undergoing hypothermia under the clinical conditions of its practical usage in the operating room. Considerable variability in vasomotor and cardiac responses was encountered, indicating that uniform behavior of patients to this agent is not to be expected in the relatively uncontrolled operating room setting; therefore, it should be used conservatively, particularly in critically ill patients in whom unexpected reactions may be disastrous.
